GAS-LOG.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed May 4. 1905. Serial No. 258,866.

T0 at whom it may concern:

Be it known that I, VICTOR, I. RIoHARDs, of East Orange, New Jersey, have invented certain Improvements in Gas-Logs, of which the following description, in connection With the accompanying drawings, is a specification, like letters on the drawings designating like parts.

This invention relates to gas logs and has for its object the provision of a log constructed to consume completely a small amount of gas in an odorless manner and to present a burning surface of large apparent area, these effects being secured in large measure by improvements in construction effecting thorough distribution of the gas within the log, and other features which will be illustrated and described fully in the accompanying drawing and specification and pointed out in the claims.

In the drawing, Figure 1 illustrates in perspective a gas log in the construction of which my improvements have been embodied, the same being partly broken away to show the interior construction and Fig. 2 is a cross section of the same taken on the line 22, Fig. 1.

In the embodiment of my invention se lected for illustration and description to enable a ready and complete understanding of my improvements, the reference letter a designates a hollow member serving as the burner log, for which purpose it is provided with burner apertures 11, c, in communication with the central cavity (Z which runs substantially throughout the entire length of the log.

In gas logs it is the usual custom to introduce the gas at two points not very far from each end, but I have found thatthe tendency of the gas is to go toward the center and not to reach the burner apertures at the ends, through which air is drawn in and frequently gas escapes on account of the lack of flame at the ends. In accordance with my invention therefore I provide an auxiliary distributing chamber 6 running lengthwise of the main chamber and preferably having its apertures f adjacent each end of the main chamber, the gas being introduced to the auxiliary chamber in the usual manner preferably through a nipple g to which a supply pipe can be attached. It will be obvious that the gas is discharged near the end burner apertures, so that they are sure to be fed, but the normal tendency of the gas being toward the middle of the log, as already noted, there is a uniform distribution of the gas to all the burner apertures, so that there is no chance for escape of gas unignited. The tube 0 also furnishes the required amount of space in which to properly mix the air and gas, before same is introduced to the burner space. This is lacking in the ordinary logs.

Passing to another important feature of my invention, it will be observed that the burner log instead of being approximately round and having a connection or connec tions therefrom, to one or more logs grouped above it, thus harassing the free distribution of gas over the burning surface of the various logs, as is usual, is extended rearward and upward, having the burner apertures c directed upwardly as best seen in Fig. 2. The log members h,i and It may be therefore made of non-burning construction, being grouped in such a way that the flame from the lower burner apertures b will lick up around the front of the member 7L while the flames from the burner apertures 0 will lick upward between the members h and i and between the members 'i and Ir, presenting an appearance such as the logs would present if they were all burner logs. I prefer to make all these logs of non-porous clay and also the auxiliary tube or chamber 6, which may be formed separately, and inserted permanently within the main chamber d, the whole forming a unitary structure of clay.

The constructional arrangement described, it will be understood readily by those skilled in the art, providesthat a minimum quantity of gas fed to the chamber (Z will be consumed thoroughly With amaximum flame effect, and a minimum chance for escape of gas, it being the only burning chamber, and having no connection to other burning members as is usual,

so that the log is practically odorless.

and described nor in general otherwise than as set forth in the claims read in connection with this specification.

What I claim and desire to secure by Letters Patent is 1. A gas log consisting of a unitary structure composed of clay and having a fuel delivery space provided with. a separately formed auxiliary gas delivery tube of clay inserted permanently within said space and arranged to discharge the gas adjacent each end of said log, within said space, and burner apertures distributed over the surface of said log, said apertures receiving a substantially uniform supply of fuel respectively from said space, substantially as described.

2. A gas log consisting of a unitary structure composed of clay and hollowed interiorly to form a single fuel delivery space in communication with a large number of burner apertures piercing the walls of said log, and an auxiliary tube of clay formed separately and inserted permanently within said space and open at each end to'deliver fuel to said space near each end of the latter, said tube having a medial fuel inlet, substantially as described.

3. A gas log comprising a pile of artificial log members including an upper group of non-burning log members and a lower or burner log member having a fuel space in communication with burner apertures some of which deliver fuel forward through the front of said burner log member, and others deliver fuel upward between said superimposed group of non-burning log members, the flames from said burner log member giving both it and said superimposed log members the appearance of burning, substantially as described.

4. A gas log comprising a group of artificial log members one of said log members being a burner log member projecting forward from beneath another of said log members and having an extension upward between still other of said log members, said burner log member having burner apertures in said lower and upper portions respectively, and said other log members being of non-burning construction, substantially as described.

5. A gas log comprising a group of arti ficial log members forming a unitary struc ture composed of clay and including a burner log member, a plurality of non-burning log members, and a log member having a chamber to contain and evaporate water or the like, substantially, as described.

6. As an article of manufacture, a gas log comprising a burner log member, combined with an evaporating chamber formed integrally therewith, and both of said log members being composed of non-porous clay, substantially as described.

Signed at New York in the county of New York and State of New York, this 26th day of April A. D. 1905.
